I recently downloaded the Raytheon Beechcraft/Hawker 400A/400Xp from you company and followed the instructions on the installation and readme.
I have FSX Steam Edition so I had to take the aircraft files directly to my Sims Objects/Airplanes file in FSX.
I was able to load it a couple times and run the trust permissions for the aircraft on FSX, but the system doesn't seem to want to stabilize with the aircraft I downloaded.
I load all other aircraft just fine, I was able to check out the Hawker 400 XP for a very brief while, but now FSX just closes down when I try to load this $30some from your company.
Please let me know that you have a fix or know what's going on. Otherwise my FSX is very stable and it's just an issue with loading your software.

it didn't point to the steam path. According to the readme the default was Microsoft Games/Microsoft Simulator X and that was true. It had it's own Sim Objects/Aircraft folder in there with the files i needed/ In order for the aircraft to show up on my FSX Steam Edition I had to move the main aircraft files to the built in Sim Objects/Aircraft folders in my FSX Steam Edition.

The installer was set to FSX Boxed but you could/should have over ridden the path either with cut/paste into the path window or by cicking the button to the right of the path window and pasting this: C:\Program Files (x86)\Steam\steamapps\common\FSX
